UNITED STATES WILLIAM ATTERBURY, OF PORTLAND, OREG-N.

SIGNALING DEVICE.

Application led November 11, 1922. Serial' No. 600,389.

To' all 'whom z't may concern:

Be it known that I, VVILLTAM E. ArriennUnY, a citizen ofthe UnitedStat-es, residl ing at Portland, in the county of Multnomah and State ofOregon, have invented a new and useful Signaling Device, of which thefollowing is a specification.

My invention relates to improvements in signaling devices forautomobiles in which 0 the intake manifold is connected with a right andleft signal by means of a manually operated valve on the instrumentboard.

The objects of my invention are to provide a mechanism whereby right andleft signals can be given by the simple shifting of a lever.

Another object is to provide an apparatus which is simple to constructand `easy to manipulate. A j

2U Further objects and advantages are to be found in the constructionand arrangement of parts as will be described hereinafter in thespecification and particularly pointed out in the appended claim.

i I attain these objects with the mechanism illustrated in theaccompanying drawing in which: Fig. 1 illustrates the generalarrangement ofmy device, parts thereof being shown in section. I

Fig. 2'is a vertical cross section through the valve illustrating thearrangement of the parts.

Similar numerals refer to similar parts throughout the several views.

Attached in any suitable manner to the instrument board of an'automobile is a valve composed of a switch lever 1, a disk 2 rotated bythe switch lever, and a housing 3 for the disk. Extending radially fromthe housing are the pipes 4, 5, 6, 7, and 8. The pipe 6 at the center isconnected with the intake manifold, so that the suction from the latterwill first be transmitted to a chamber 9 in the housing formed byv thecutaway edge in the disk, and thence through such other pipes as maycommunicate with the chamber.

Traversing the automobile from one side to the other is a tube 10 whichis divided in half by a center wall 11. contains a piston 12, and asuitable signal' 13 telescoped in the end of the tube 10 and attached tothe end of the piston rod 14.

Each half b line of the housingl at The wall 15 limits the outwardmovements of the piston.

The pipes from the housing 3` are connected with-thel tube 10 in such amanner that, when theswitch lever l stands in neutral position, thesuction from Vthe intake manifold will be transmitted through the pipes5 and 7 `and draw the pistons toward the center wall, thus keeping thesignals concealed in the tube 10. v

If the switch lever be thrown toward the right as' indicated by thedotted line 16, suction in the pipe 5 will still be maintained and holdthe left signal in concealment, but suction from the pipe 7 has beenshut olf, and communication with the pipe 4 has been establishedinstead, this draws the right piston outwardly into the dotted position17 and the signal appears either in the shape of a painted or anilluminated arrow. Reversal of the switch lever withdraws the right andprojects the left signal.

The pins 18 limit the throw of the switch lever.

Having thus described my invention it will be seen that my objects havebeen accomplished, and, though I have shown the preferred form ofconstruction, I reserve to myself the right to make minor changesproviding I do not violate the spirit and principle of my invention.

I claim:

In a signaling device for automobiles, the combination of a horizontaltube extending from one side of the automobile to the other, a walltraversing the tube diametrically at the center, a second walltraversing the tube diametrically on each side of the center wall, saidsecond wall delimiting an air tight compartment on each side ofthecenter wall, and a piston reciprocating within each compartment, with afiat circular housing below the tube, the axis of said housing lyingwithin the plane of the center wall, a flat circular disk rotating airtight in said housing, said disk having a crescent shaped section in thetop edge cut away thusyleaving an air tight chamber between disk andhousing, a suction 1nlet entering the rim of the housing radially andcommunicating with the er, a suction outlet chamat the medial centereach side of the inlet and normally communicating with the chamber, eachsuction outlet proceeding toward the tube and terminating in thecomnamed outlet crossing the plane of the center partment correspondingto the respective wall and termnatin in the compartment on outlet andbelow the lowest piston inward the opposite side a ove the highestpiston l0 stroke, a. second suction outlet at the medial outward stroke.
